Congratulations! You have purchased a high quality stereo
loudspeaker. When matched to comparable electronic equipment,
expect years of quality high delity sound. Our belief is that music
matters and we are focused on delivering superlative music
reproduction everywhere in your home.
The following manual is designed to give you, the installer or owner,
basic information as to the speaker’s installation and operation. It is
beyond the scope of this manual to go into all the details that must
be taken into consideration in a sophisticated high delity system.
When installing the wiring and speakers it is important to adhere to
all local codes and regulations. Consulting a professional will help to
maximize your system’s performance.
If you have any questions that are not answered by this manual,
contact your local dealer for assistance. For the most current
information please visit:

GENERAL DESCRIPTION
These two-way speakers have specially designed woofers with
linear long throw butyl rubber surrounds for long life and superior
damping. Pivoting Dome Tweeters are utilized for excellent high
frequency dispersion throughout your entire listening environment.
SHIPPING DAMAGE
Each speaker is thoroughly tested before it leaves the factory.
However, in shipment, accidents may occur. Please inspect your
speakers carefully when you receive them to make sure there
is no damage. If there is, please notify your dealer, or supplier
immediately for assistance. If you received your speakers by public
transportation, report the damage at once to the shipping company.
AMPLIFIER OPERATION
These speakers will perform well with ampliers from 5 to 125 Watts
RMS. However, damage to the speakers can be done by ampliers
of nearly any power rating if the amplier is overdriven into clipping.
“Amplier clipping” is a phrase used to describe a condition when,
because of the volume demand, an amplier is being asked for more
power than it can give. Clipping causes distortion of the audio signal.
If you should hear an unusual amount of distortion at high listening
levels then consider reducing the volume. DAMAGE DONE TO A
SPEAKER BY CLIPPING IS NOT COVERED UNDER THE WARRANTY.
SPEAKER PLACEMENT
Placement of In-wall Speakers should be carefully considered.
Please contact a professional for assistance if you are
uncomfortable with the planning or installation process.
Ideally, the speakers should be located where they will provide the
best possible sound and ease of installation. It is beyond the scope
of this publication to discuss all of the various aspects of speaker
placement but here are some helpful suggestions.
For more bass, place the speakers between 18 and 36 inches from
an adjacent wall as measured to the center of the speaker. Avoid
placing the speakers less then 18 inches from an adjacent wall. When
placing speakers near a corner, avoid locating them an equal distance
from the two adjacent srfaces.
When used in a home theater the front left and right speakers should
be separated from each other a distance of 0.8 to 1.2 times the seating
distance (assuming they are on the same plane as the center speaker).
For example, if the seating position is 10 feet from the viewing screen
and/or center speaker then ideally the distance between the left and
right speakers should be somewhere between 8 and 12 feet, (10 x 1.2ft
= 12ft). MTM style speakers are best installed in portrait orientation.
However, landscape is often used for the center speaker for aesthetic
or clearance purposes. If the speakers are located behind an
acoustically transparent screen then all the speakers should be
oriented portrait style. Tweeters may be aimed toward the listening
area by pressing the lens area along side the tweeter dome.
WIRING
To achieve maximum performance we recommend that the speaker
cable be at least 16 gauge or larger for runs over 50 feet (15m) and
that the cable be double insulated. A CL-2 or CL-3 rated cable may
be required. Check local codes. “Zip cord,” which is single insulated
and is often made with clear insulation, should be avoided as it is not
as durable. Allow about 2½ feet (0.8m) of free cable at the speaker
cut-out and sufcient length at the other end to reach the electronics.
Having to add extra cable later can be tedious and time consuming.
Avoid bundling speaker cables parallel to electrical cables for
extended lengths. Though the impedance is low and the likelihood of
interference low, this may help reduce hum and RF interference. When
securing the cable, use care not to staple or nail through the electrical
conductors. Doing so could result in a short that might damage the
electronics.
When connecting your speakers, make sure proper polarity (phasing)
is maintained. Simply put, this means ensuring the same wire which
is connected to the positive terminal of the amplier has its other end
connected to the positive terminal of the speaker. It is important to
check this on all speakers. If the connections on one of the speakers
are reversed, (out of phase) the sound quality will be impaired.
INSTALLATION
If the drywall has not yet been installed a Rough-in-Bracket (RIB-LCR)
may be used to reserve the speaker location on the wall. The RIB-
LCR brackets are available from the distributor or dealer where the
speakers were purchased. When these brackets are used the holes
are cut when the drywall is installed. The cable can be tied off on the
bracket after securing the cable to a nearby joist.
If the drywall is installed and the speaker locations have not yet been
established, then do so now. Assess the wall for possible concealed

Insert the speaker into the frame and install the eight screws (see g. 4).
The mid and high frequency levels can also be adjusted as desired using
the mid frequency (MF) and high frequency (HF) switches. The MF switch
changes the output level in the lower midrange. Increasing the level
adds more body to the midrange, while decreasing it creates a lighter
presentation. Decreasing the level may benet the sound reproduction
when the speaker is mounted close to another surface.
The HF switch changes the output level of the upper midrange and high
frequencies. Increasing the level creates a brighter presentation while
decreasing it produces a softer one.
The grilles can be painted using multiple light coats of spray paint. Custom
color spray paints are available from specialty companies. Contact your
dealer for more information. The grilles should be removed from the
speaker and painted in a clean environment to prevent contamination. It
is best to go around the grilles and apply the paint from multiple angles.
DO NOT remove the scrim cloth from the backside of the grille. It is not
replaceable.
Attach the grilles to the speakers and enjoy. Should you wish to remove
the grilles from the speakers pull at the grilles' edge. Initially there will be
signicant resistance because the grilles are magnetically attached.

obstructions such as wiring,
plumbing, etc. Inspect the
backside of the wall, the attic,
and/or the crawl space if
available for clues to possible
obstructions. Use inspection
holes with inspection tools
(camera, mirror, ashlight,
etc.) if absolutely necessary.
Use a “stud nder” to locate the positions of the studs.
The AKF-5.25LCRS is shipped with a horizontal Retro
Ring and a vertical retro ring . With retro ring
, the edge of the speaker opening must be at least 1/2"
(13mm) away from a stud
if the speaker is installed
in the portrait orientation.
Retro ring is for
mounting closer to the
stud when in the portrait
orientation.
Once the speaker locations are established use
the cardboard template (the outside of the inner
cardboard rectangle) to mark the speaker cut-
out. The dimensions for the cut-out are listed on
the previous page. Using the proper tool, cut the
appropriate sized hole in the wall. On drywall,
clean cuts can be made with a drywall saw.
If the cable has not yet been run, do so once you have access to the wall’s
interior.
To aid in speaker performance, a brous material, such as berglass,
may be placed behind the speaker. This may also help to reduce
unwanted sound from being transmitted into adjoining rooms. If the
wall space has blown or loose insulation, care must be taken to prevent
the loose insulation from entering the back of the speaker. This can be
accomplished by placing a batt of berglass insulation over the back of the
speaker.
As the diagrams above show, the speakers utilize a metal Retro Ring which,
after tightening the 4 provided screws, acts as a clamp to hold the magnet
frame in place. Note: Use only the 4 outer holes for mounting the frame.
Install the frame and retro ring assembly by passing the metal retro ring
through the cut-out as illustrated in gures 1 & 2. The magnet frame
should t cleanly, without interference, in the cut-out hole. If the hole is
a little small then trim the hole as needed. Lightly tighten the screws to
secure the retro ring against the back of the wall (see g. 3). Use care not
to over-tighten the screws or the frame may become distorted.
Pull the end of the cable out of the wall, strip back a section of the jacket
as needed, and then expose ½" (13mm) of each conductor. Connect the
wire to the terminals on the back of the speaker assembly, observing
polarity (+ & -).
